A new high-speed photorecorder, ITMGT-device (ionization type magnifying glass of time), is presented which unlike the well-known analogs operates in a wide spectral range of 1.3 - 10.6 micrometers and is intended to record frame by frame the beam structure of laser IR radiation. ITMGT has a wide dynamic range (not less than 300) and high sensitivity (10-4 - 10-5 J/cm2) in a wide spectral region. It provides frame recording with an exposure length of a frame of 10 - 50 microsecond(s) , framing rate up to 100 Hz, and up 100 frames for one recording cycle. It was successfully used to measure divergence and energy density distribution at the end of pulsed and pulsed-periodic IR lasers, in facilities for laser isotope separation and also in development of new industrial technologies for processing, welding, and cutting of materials with the help of high- power laser radiation.
